Whether the $2.6 billion mission is a replacement or a supplement to the president's planned human mission to an asteroid is unclear. The proposal was first developed by the Keck Institite in April, 2012 and has achieved new impetus due to the meteor incident over Russia and new fears of killer asteroids."
